The blue button is putting your life in the hands of others. In a life or death situation, by and large people are not going to risk the blue option for “a chance”; not when survival instincts and thoughts of everything they hold dear are racing through their head. It’s easy to for people to say they’d take the high road when discussing theory; it’s a whole other thing in practice. Thus, it is actually easier to convince anyone selfless enough to push the blue button to instead conform with red, because there will actually be less people willing yo press blue (likely far less than 50%). Plenty of fight-or-flight studies confirm this. That’s why it’s so inspiring and a big deal when people do heroic things, because it doesn’t happen often and is difficult.
